I applied online. I interviewed at SpaceX (Brownsville, TX) in Feb 2026
Interview
First interview was ~30 minutes, mostly talking about the salary and culture of working there. Some light technical questions like what is Young's Modulus and stuff like that. Second round was more about wanting to see how you think, they set up a test failure scenario and wanted me to walk through how I would figure out what the issue was/mitigate it in the future.
The first step typically involves a call with HR or a recruiter. They’ll ask basic questions about your resume, motivation for applying, and why you're interested in the company. It’s also an opportunity for them to confirm logistical details, like availability and compensation expectations.
Resume walkthrough and technical questions. Wanted to know basically the entire scope of my academic knowledge. Ask fundamental circuits and transistor questions. Asked me about design choices in nearly all my projects.
